Definitions

• the invention relates to a device for ejecting liquid from a wiper body, which is held to form a wiping surface on a wiper head of a surface cleaning device, with a container in which a wiper body holder receiving the wiper body and a drive device are arranged, the wiper body holder being arranged by means of the drive device an axis of rotation is drivable.
• a wiping body for example a wiping pad or a wiping covering, which is held on a wiping head to form a wiping surface, is often used to clean a soiled surface, in particular a floor surface.
• the wiping body is moved with its wiping surface along the surface to be cleaned and dirt is thereby absorbed.
• the wiper body is then usually washed out and wrung out.
• WO 92/14394 A proposes to place the wiper body on a wiper body holder, which is then set in rotation so that liquid is thrown out of the wiper body due to the centrifugal forces acting on it.
• Such a procedure has the advantage that the user does not come into contact with the cleaning liquid.
• the known device requires not inconsiderable energy consumption in order to reliably dehumidify the wiping body.
• the object of the present invention is to develop a device of the type mentioned at the outset in such a way that the dehumidification of a wiper body can be carried out with less energy consumption.
• the wiper body holder forms a receptacle into which the wiper body can be inserted with the surface normal of the wiping surface oriented at an angle to the axis of rotation.
• the wiper body holder holds the wiper body with an angular, ie oblique or perpendicular to the axis of rotation wiping surface within the container, i.e. H. the surface normal of the wiping surface is not aligned parallel to the axis of rotation, but is at an angle to the axis of rotation. It has been found that liquid droplets can be thrown out particularly effectively by such an alignment of the wiping surface.
• the device according to the invention is consequently characterized by a higher efficiency. This makes it possible to achieve effective dehumidification of the wiper body even at relatively low speeds and consequently with relatively low energy consumption.
• the receptacle receives the wiping body with the surface normal of the wiping surface oriented perpendicular to the axis of rotation. This enables a particularly compact form of the spinner.
• plate-shaped wiping bodies can be dehumidified in an advantageous manner, which form a wiping surface both on their top side and on their underside and can therefore be used on both sides.
• wipers are usually on a Nem wiper body holder held on the side of a handle or handle.
• the wiper body carrier with the wiper body held thereon can be pivoted relative to the handle such that, alternatively, the top or the underside of the wiper body carrier faces the surface to be cleaned.
• This pivotable mounting of the wiper body carrier on the handle makes it easier to insert the wiper body carrier together with the wiper body held thereon into the receptacle of the wiper body holder such that the surface normal of the wiper surface is oriented perpendicular to the axis of rotation of the ejection device.
• the receptacle comprises a guide into which the wiper body can be inserted.
• the guide facilitates the insertion of the wiper body.
• the guide preferably has two U-shaped guide elements that run parallel to one another and hold the wiper body between them.
• the guide elements are preferably held at the opposite ends of a guide support aligned parallel to a bottom surface of the container.
• the wiper body can be inserted particularly easily into the receptacle of the wiper body holder if the guide elements are aligned parallel to the axis of rotation.
• the wiper body holder can be rotated manually.
• the drive device coupled to the wiper body holder can have mechanical drive elements with a user of the ejection device operated crank or a foot pedal. It is particularly favorable if the drive device has mechanical deflection elements for deflecting a translatory movement of the foot pedal into a rotational movement of the wiper body holder.
• the drive device comprises a drive motor, preferably an electric motor.
• the drive motor is assigned a rechargeable energy supply unit. This enables the centrifugal device to operate independently without the need to ensure a mains supply.
• the drive device is arranged inside the container below the wiper body holder and preferably at a distance from a bottom wall of the container.
• the area below the drive device can consequently serve as a receiving space for the liquid ejected from the wiper body.
• the drive device on the bottom wall of the container, the drive device not covering the entire area of the bottom wall, so that a receiving space for the ejected liquid can be provided on the side next to the drive device within the container.
• the drive device held on the bottom wall can also be positioned at a distance from the wiper body holder, forming the receiving space between the two components. It is advantageous if the speed of the wiper body holder is adjustable. This makes it possible to set different speeds depending on the desired degree of moisture that the wiping body is to have after spinning. For example, a selector switch can be provided with which the user can select a specific speed.
• the speed is continuously adjustable, for example in a range between 250 revolutions per minute and 500 revolutions per minute.
• a maximum spin time of the wiper body holder can be specified, after which the rotary drive of the wiper body holder can be switched off automatically.
• the user can use a selector switch to choose between different spin times. In particular at a given speed, the selection of the spin time gives the user the opportunity to adjust the degree of moisture of the wiper body as required.
• the wiper body holder has a switching element which, after the wiper body has been inserted into the wiper body holder, activates the rotary drive.
• a key switch is preferably used as the switching element. It has proven to be particularly favorable if the switching element is based on can be actuated smoothly, for example it can be designed as a reed contact.
• the use of a switch which can be actuated manually by the operator of the ejection device can be provided, for example in the form of a main switch or emergency stop switch.
• the wiper body holder is coupled to the drive device via a slip clutch. This enables the wiper body holder to be held in place when the drive device is active, without there being any risk of injury.
• the container comprises a partition for dividing the container into a centrifugal area receiving the wiper body holder and a washing area receiving a cleaning liquid for washing the wiper body. This gives the user the opportunity to first immerse the wiper body several times in the cleaning liquid during cleaning and thus to wash the wiper body. The wiper body can then be inserted into the wiper body holder in the centrifugal area and set in rotation to eject the cleaning liquid.
• the centrifugal area receives both the wiper body holder and the drive device.
• the Drive device positioned within the washing area and is connected via coupling elements to the wiper body holder arranged in the centrifugal area.
• the device comprises a spray device for spraying the wiping body inserted into the wiping body holder.
• a spray device for spraying the wiping body inserted into the wiping body holder. This makes it possible to spray the wiping body with cleaning liquid, while at the same time rotating it. It can be provided, for example, that the wiper body is first rotated at a low speed and at the same time sprayed with cleaning liquid, and that the cleaning liquid is then thrown out of the wiper body at a higher speed.
• the spray device preferably comprises at least one spray nozzle which is in flow connection with a feed pump. It is advantageous here if liquid can be pumped from the area below the wiper body holder to the spray nozzle by means of the feed pump. This means that liquid which was spun out of the wiping body in a previous spinning process can be sprayed onto the wiping body for washing in a subsequent spinning process.
• the spinner device comprises a storage chamber for unused cleaning liquid and if liquid is pumped from the storage chamber to the spray nozzle by means of the feed pump. that can. This allows the wiper body to be sprayed with unused cleaning liquid for washing.
• the container of the centrifugal device can be closed by means of a container lid. This not only reduces the risk of a user accidentally reaching into the container during the rotation of the wiper body holder, but it also enables the drive device to be switched on and off depending on the position of the container lid by the container lid having an electrical switching element interacts.
• the container lid can be hinged to the container, for example, and the switching element can be designed as a button that switches on the drive motor when the container cover is closed and that switches off the drive motor when the container cover is opened.
